Protists&Fungus

Transcript: Fungus-like Zygotes are fungus that grow on things like mold. Lichens Animal-like Animal like protist move with a pseudopod, cilia, flagella. Fungus-like protists cannot make their own food. They adsorb their food, and they digest their foods after they eat it. Imperfection Protists&Fungus Club fungi Lichens are growth on rocks, trees, wall. Zygote PROTISTS Club fungi are mushrooms that we eat, and that are safe. Sac Protists Free living organisms. Plant-like Plant-like protists contain chlorophyll and make their own foods. FUNGI Sac are fungus that grows on trees! Imperfection is penicillin, and penicillin is an antibiotic.

Fungus/Protists

Transcript: They live in water. How are fungi useful? A flagellum is a tsil used to propel the pretists . What is the formulation for yeast? Protist question # 1 what sickness are caused by protist? Cilia are little hair that help the protist move through liquid. What is the difference between a saprophyte and a parasite Fungus and Protist!! a saprophyte lives off a dead organsim! and a parasite lives off a living organsim! Portist can cause sickness like malrai,sleeping sickness. How are fungi harmful? They decompose other organism to eat!. By Cameron Johnson Fission,conjugation. .Fission is like cloning. but conjugation is when two protist join together and exchange cytoplasm then separte. How do protist reproduce? What is the diffrence between the two methods? No fungus are not plants because they do not use photosythesis. Fungi are useful by: Mold-penicilin,Blue cheese Mushroom-Food Yeast-Beer,bread How does fungus eat? What is a flagellum What are cilia? The fungus reproduceThey use spores !! Paramecium A pseudopod is a fake foot. What are pseudopods? Euglena Is a fungus a plant? why or why not? It can casue Athletes foot, Ring Worm, Mold. How does fungus reproduce? Amoeba Used in fermentation - the process when yeast,sugar and warm water produce CO2 and alcohol. Where do protist live?

Fungus Like Protists

Transcript: Sexual Reproduction: - Two haploid amoeboid cells fuse - Engulf surrounding amoeboids to form a single organism called a macrocyst. - Macrocyst then undergoes meiosis and mitosis and releases haploid individuals Cellular Slime Molds - Over 500 species - Filamentous protists that absorb their food from the surrounding water or soil - May invade the body of another organism to live - Extend fungus-like threads into host's tissue and absorb nutrients - Cell wall is not composed of Chatin - Instead it is made of compounds and glycan - Nuclei are diploid - Begin their life cycle as an amoeba like cell - Feed from engulfing food particles and nutrients into their cytoplasm by a process called Phagocytosis - Single Cells with thousand of Nuclei - Individual flagellated cells swarm together and fuse - One large bag of cytoplasm with thousands of diploid Nuclei Plantae - Most of their lives as free-living amoeboid cells - Feed on tiny bacteria or yeast cells - When food supply is gone, produce spores that can survive harsh conditions Slime Molds - Eukaryotic organisms - All very different from one another - Classified into 3 groups - Plant-like Protists - Animal-like Protists - FUNGUS-LIKE PROTISTS - Can be autotrophic or heterotrophic Phylum Arcrasiomycota "Slime Nets" Water Molds Water Molds: Oomycota Two Main Groups: Slime Molds and Water Molds What Are Fungus-Like Protists? Fungus Like Protists - Heterotrophs that absorb nutirents from living and dead organisms, and wastes - Grow in damp, organic rich place Water Mold Plasmodial Slime Mold: Phylum Myxomycota Cellular Slime Mold: Phylum Arcrasiomycota Reproductive steps: 1. Send out chemical signals to attract other cells of the same species 2. Thousands of cells aggregate into a large sluglike colony that functions as a single organism, called a Pseudoplasmodium 3. Produces a fruiting body, slender reproductive structure that produces spores 4. Spores are scattered by the wind 5. Each spore gives rise to a single amoeba-like cell starting the cycle all over again Plasmodial Slime Molds Labyrinthulomycota Eubacteria True or False? Water Mold: Phylum Oomycota By: Jako Ho 2 Types: Phylum Myxomycota Interesting Fact: Animalia Slime Mold Organism Classification System Summary - Phytophthora infestans caused the Great Potato Famine - Killed nearly a million people in Ireland in 1846–1847 - Wiped out the country’s potato crops - 1.5 million Irish to flee the country - Potato crops were clones of a few original imports from South America, they had no natural ability to resist the pathogen. - Heterotrophic organisms that absorb nutrients from dead or decaying organic matter - Grow in damp, organic-rich sites -Rotting logs or decaying plants on the forest floor - Produce spores - Lack Chitin in their cell walls - Classified into mainly 2 groups Archaebacteria Fungi Protists 1. Plasmodial Slime Molds spend most of their lives as free-living cells until food supply is gone. 2. Fungus-like protists are very similar to Fungi, especially when one compares their cell walls. 3. There are over 500 species in Oomycota. 4. A species from the Cellular Slime Mold caused the Irish Potato Famin in 1846. 5. A Pseudoplasmodium is a multicellular mass that is resulted from the collection of many seperate amoeboid cells. 6. Plasmodial Slime Molds feed by engulfing small particles of food into their cytoplasm. 7. Fungus-liek protists can be heterotrophic and autotrophic at times. Fungus-Like Protists

fungus-like protists

Transcript: acrasiomycota is a family of slime molds. oomycota form a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms. myxomcota is a class of itself a grouping of slime molds that contains 5 orders,14 families,62genera and 888 species Major phyla Water and slime molds history fungus-like protists Fungus-like protists Angely Gonzalez, Ashlee Caballero,Solir Mejia,Michael Mazingo Fungus-like protists are protists that absorb their food from dead organic matter. They are grouped into 2 groups ,slime molds, and water molds. They have a cell wall just like a plant. Many of them live in single-celled organisms. Evolved from bacteria about 2 billion years ago one slime mold is a pretzel slime mold algae is also in this group it has a green pigment chlorophyll,which is used for photosynthesis

Fungus-like Protists

Transcript: Harmful & Helpful Usually do not move but some develope movement at some point Slime Molds Downy Mildews Meagan and Grace To get rid of Slime molds you have to alter it's enviroment, you cannot kill nor eliminate it with chemicals They grow in moist places such as rotting logs or decaying plants They pose no threat to plants, animals or children Water Molds Fungus-Like-Protist share many feature with Fungi Water molds or Oomycota caused the Great Potatoe Famine killing nearly a million people in Ireland from 1846-1847 Slime molds use spores to reproduce and have cell walls which are made up of chitin. Harmful Downy Mildew is a type of Water Mold and is considered a dieses for crops. Heterotraphs, meaning they must obtain food outside themselves. Fungus-like Protists Helpful Characteristics of Fungus-Like-Protist Fungus like protists reproduce by using their production of spores Common mold, appears in our world as a fuzzy, cobweb-like growth over organic matter. How are Fungus-Like-Protist Fungus-like Protists Types of They feed on bacteria and other micro-organisms They may be beneficial to the further development of pharmaceutical, medical drugs

FUNGUS- LIKE PROTISTS

Transcript: § Phylum Acrasiomycota § Spend most of their lives as free-living cells resembling soil amoebas § When food supply is gone, produce spores that can survive harsh conditions § Reproductive steps: 1. Send out chemical signals to attract other cells of the same species 2. Thousands of cells aggregate into a large sluglike colony that functions as a single organism 3. Produces a fruiting body, slender reproductive structure that produces spores 4. Spores are scattered 5. Each spore gives rise to a single amoeba-like cell starting the cycle all over again Acellular Slime Molds Respiratory Metabolism FUNGUS- LIKE PROTISTS Use to be classified in the kingdom fungi but is now classified under the kingdom protista. Because the fungus-like protists move one time in their life and fungi do not, they are no longer classified in that taxonomic category. Reproduction At some stages of life are unicellular, at others is multicellular Body Plan Resources: Circulatory Help to decompose and recycle nutrients in an ecosystem. Harmful because they can cause disease in organisms. - Asexually: mate is not needed, they form spores - Sexually: takes place in specialized structures that are formed by hyphae. Antheridium produces male nuclei and oogonium produces female nuclei. Fertilization takes place and spores form a new organism. Water Mold Use the process diffusion from the external environment through their cell walls and/or membranes. No circulatory system present due to their thin cell membrane, all the nutrients they need are transported through diffusion or active transport. Slime Molds Digestion Water Molds Cellular Slim Molds § Phylum Myxomycota § Begin their life cycle as an amoeba-like cell § When they aggregate, cells fuse to produce structures with many nuclei or plasmodia. § Can grow as large as several meters in diameter § Sporangia (small-fruiting bodies) spring up from the plasmodium § Haploid spores scatter and germinate forming amoeba-like cells § Cells fuse into a sexual union to produce a diploid zygote and the cycle is repeated Nervous - Intracellular: The digestive system that fungus-like Protists has, uses a phagosome. This is a vacuole that is formed around a particle/food substance in order to absorb nutrients from the particle. The process is known as phagocytosis. Slime Mold Helpful vs. Harmful - Heterotrophs with cell walls - Usually dead organic material What are fungus-like protists? Do not have a nervous system, however, they communicate by sending hormones to one another. Since protists are either unicellular, which means they can't have specialized cells as they only have one cell; or they are multicellular without specialized tissue, that also means they wouldn't have a nervous system as that would rely on specialized tissue. http://www.henry.k12.ga.us/ugm/academic/Team702/liberatore/SAGE%20Website%20for%20Kingdoms/Amie%20and%20Jena/Fungus.htm http://jcareywi.tripod.com/id23.html http://www.cliffsnotes.com/sciences/biology/plant-biology/protista/fungi-like-protista http://www.lanesville.k12.in.us/LCSYellowpages/Tickit/Carl/protists.html They are protists that absorb their food from dead organic matter. Most fungus-like protists use psuepods, (“false feet”) to move around. Lack chitin in their cell walls Three types: ► - cellular slime molds ► - acellular slime molds ► - water molds Unicellular Recycle organic material Found on forest floors or a backyard compost pile At one stage in their life cycle, they resemble amoebas In the other stage, they form moldlike clumps that produce spores Body resembles that of fungus Divergent Event § Resembles white fuzz growing on the surface of dead fish in the water § Phylum Oomycota § Thrive on dead and decaying organic matter in the water § Some are plant parasites on land § NOT true fungi ► Cell walls made of cellulose and produce motile spores § Reproduce both sexually and asexually ► - Asexual reproduction involves hyphae (thin filaments) which develop into zoosporangia (spore cases). Flagellated spores swim away in search of food. Spores develop into hyphae when they find food and grow into a new organism ► - Sexual reproduction takes place in specialized structures that are formed by hyphae. Antheridium produces male nuclei and oogonium produces female nuclei. Fertilization takes place and spores form a new organism.
